WIFI - Solving Error: Reason: 3=DEAUTH_LEAVING

[maja_ldm]

I freshly installed Debian Stretch and I'm trying to get a wirelss internet connection from the same usb dongle that was used during the netinst installation of the system. The same dongle worked when Debian was installed and still works on a Windows 10 installation on the same machine. According to lsusb the dongle's name is D-Link Corp. DWA-121 802.11n Wireless N 150 Pico Adapter [Realtek RTL8188CUS] and it requires the driver rtlwifi/rtl8192cufw_TMSC.bin which is installed as part of the non-free package firmware-realtek_20161130-4_all.deb and loads correctly according to the dmesg output.

The device name is an unusually long string: wlx10bef501e1cd. The same name was used successfully during installation of Debian (connecting through ipv6). During previous start up of the system I recorded the following output: rtl8192cu 1-3:1.0 wlx10bef501e1cd: renamed from wlan0, but I can't find that same line in more recent attempts. Also, in a previous installation (which used mate instead of Gnome) the following error appeared several times, indicating that the name was too long, but in the current installation this output has disappeared:

wlx10bef501e1cd: aborting authentication with 90:94:e4:e7:99:cc by local choice (Reason: 3=DEAUTH_LEAVING)

This is an example output of attempting a connection through the dongle:

Also, after modifying /etc/network/interfaces with:

which after about a minute results in no output in the terminal and no connection established, it also results in the connection hanging indefinetely at startup as shown by the GUI with a "waiting"symbol in the connection selection and by the following output:

When the dmesg output reported Reason: 3=DEAUTH_LEAVING errors I attempted to create a permenent rule in /etc/udev/rules.d/70-persistent-net.rules with the following (after getting values from udevadm info), without success and since since I can't see the same error at start up anymore I gave up on this line.

Code: Select all

SUBSYSTEM=="usb",ACTION=="add",DRIVERS=="usb",ATTRS{product}=="802.11n WLAN Adapter",ATTR{dev_id}=="0x0",ATTR{type}=="1",KERNEL=="1-3", NAME="wlan1"

Since the dongle was used to download the system during installation I believe it can be used to connect to the internet, but I don't seem to be able to figure out how making it work. What steps can I attempt next (also, consider I'm not an experience user and I'll probably need to be spoonfed each command one by one).

Can you connect using static addresses? If so, check your router for any expired leases.

[Dai_trying]

I have a usb device with the rtl8192cu chipset and had to use a github fix to prevent the signal dropping after a few minutes, I would guess it might help you too.
https://github.com/pvaret/rtl8192cu-fixes
The readme states it is now deprecated from kernel 4.4 onwards (aimed at ubuntu but the fix works for debian), but I have it in use on a couple of machines that occasionally need to use wifi with my TL-WN822N
YMMV

I wouldn't know how to do that, but I logged in my router and verified there aren't any expired leases.

I was getting ready to install the repackaging (which was a cumbersome operation since I had zero access to the internet), but then I realized the renaming and DEAUTH error were still in the dmesg output and headed over to stack exchange to ask how to avoid the device being renamed (https://unix.stackexchange.com/question ... 488_491754), which ended up working since now I have a functional interent connection.

For further reference writing a correct renaming rule would also probably have worked.

Yea I am getting about your problem, all what I have done is to figure out about the right Wireless router and the right Router table. But as I am not sure, I don't know how to get the router table, all I can suggest is you to get the suggestions from the community member.
Thanks!

[Head_on_a_Stick]

Then calling to my internet connector, he told me that you need a right router table so that it can support your Internet cable. Then you will be installing the Wi-Fi dongle and it will work out.

This will show the routing table for your machine:

Code: Select all

ip route

The configuration is usually taken care of by the networking software (such as NetworkManager) but you can do it manually if you want.
